Percutaneous Transluminal Angioplasty of Renal Artery: Therapeutic Experience of 31 Patients
Abstract
- PURPOSE
The purpose of this study is to introduce the experience of 31 patients who had renovascular hypertension and underwent percutaneous transluminal angioplasty of renal artery (PTA).
MATERIALS AND METHODS
The subjects were 31 patients with hypertension and stenotic renal artery or arteries on angiography. The criteria of stenosis is more than 50% narrowing of the artery. The technical
results
were considered to be successful if residual stenosis is less than 50%. The clinical results were classified as cure, improvement and fail. And clinical results were analyzed according to the follow-up duration, short term (< or = 6 mo) and long term (< 6 mo).
RESULTS
Technical success rate was 90.2% (37/41) and clinical success rate were 82.8% (24/29) on short term follow-up and 84.2% (16/19) on long term follow-up. Recurred cases were 7 cases.
CONCLUSION
PTA is a safe and effective therapeutic modality on renovascular hypertension.
